sponding Signal Numbers on page 10.
Minimum Number of Crosspoint Cards and Output Cards
Because each crosspoint card manages four output cards, the number of crosspoint cards installed,
and where installed, is determined by the number and location of output cards installed. Crosspoint
cards send input information to all other crosspoint cards, so where input cards are installed is not a
factor. Output cards manage outgoing signals. Only the number of cards required to support the sig-
nals being distributed need to be installed.
The following table lists possible crosspoint card installation configurations when the NV7512 is
used as a standalone router. The table lists in which slot crosspoint cards and output cards are
installed and the minimum number required (see
Figure 1-2 on page 8 ). For a description of each
type of card, see Active Cards on page 20. This list is not exhaustive, but shows a sampling of the
wide variety of configurations that can be created. Although the examples list a full complement of
input cards (512 stereo inputs) and output cards for managing the maximum number of signals
listed (32 outputs per card), only the specific number of cards required for the number of inputs
